Safety of Short-course of NSAIDs in Pediatric Patients With CKD

The purpose of this study is to determine if non-steroidal anti-inflammatory (NSAID) use in the postoperative setting increases the risk of acute kidney injury (AKI) in pediatric patients with mild-to-moderate chronic kidney disease (CKD). The investigators hypothesize that there is no increased risk. This is currently in the process of developing multi institution collaboration within a Pediatric Urology population, intended to inform future work in a larger patient population.
